import_request_variables
(PHP 4 >= 4.0.7, PHP 5)
import_request_variables — Import GET/POST/Cookie variables into the global scope
Description
bool import_request_variables
( string $types
[, string $prefix
] )
If you're interested in importing other variables into the global scope,
such as SERVER, consider using extract().
Parameters
-
types
-
Using the types
parameter, you can specify
which request variables to import. You can use 'G', 'P' and 'C'
characters respectively for GET, POST and Cookie. These characters are
not case sensitive, so you can also use any combination of 'g', 'p'
and 'c'. POST includes the POST uploaded file information.
Note:
Note that the order of the letters matters, as when using "gp", the
POST variables will overwrite GET variables with the same name. Any
other letters than GPC are discarded.
-
prefix
-
Variable name prefix, prepended before all variable's name imported
into the global scope. So if you have a GET value named "userid", and
provide a prefix "pref_", then you'll get a global variable named
$pref_userid.
Note:
Although the prefix
parameter is optional, you
will get an E_NOTICE level
error if you specify no prefix, or specify an empty string as a
prefix. This is a possible security hazard. Notice level errors are
not displayed using the default error reporting level.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example #1 import_request_variables() example
<?php
// This will import GET and POST vars
// with an "rvar_" prefix
import_request_variables("gp", "rvar_");
echo $rvar_foo;
?>
